I want one!

I'm curious about this things beam divergence.

 

[doggy]

how do you mean?

Beam divergence - Wikipedia, the free encyclopedia


And that's a really cool gun.

Just keep in mind that these pulsed lasers are incredibly dangerous.

...and not just from the direct beam path either. The reflected energy is incredible, yet so fast you'll never see it clearly.

Would a beam expander work well with this provided you have it special coated to pass as much light as possible and take the high temperature?

There was already a thread about it http://laserpointerforums.com/f44/1-mega-watt-pulse-laser-gun-high-speed-61385.html

I'd also love to eventually get my hands on one of these. However for now it's a little low on my laser wish list, mostly because they don't come cheaply.

It could be done but it would lower the power "density" drastically unless it was some kind of 1.1000020105x beam expander.

Someone commented on his video asking about the divergence and the guy responded confirming my suspicions that this thing has horrid beam divergence. See this thing is cool but you need to take into consideration the fact that if you focus it at a specific distance and then change the distance by just a few inches or just back up 1 foot the beam is going to be extremely defocused and you wont be blasting holes in anything which is one of the reasons a legitimate laser gun capable of blasting holes in people is extremely difficult. You would need to have a beam powerful enough to be put through a beam expander and not lose power even with increased beam width. Oh and then there's the matter of a power source that will last more than one shot that isn't the size the size of a small garage. Then the issue of rayleigh scattering, cooling. When you think about it this is the most successful laser gun

Not exactly what I would call compact.

actually, id like more to see how he did it, ie flashlamps? type? , or how to get that pulse so short, its very hard to get descriptions out there...(maybe for obvious reasons)

and wouldnt proper lensing fix that divergence thing? couldnt he "straighten" the pulse like my "pen size green laser pointer so the beam is more linear, but still effective?

also if i got IR glasses for one of these would i need to like "double up" or something?

It's a Q-switched YAG laser, look at wikipedia or sams laserfaq for more info

Probably not, my guess it that it's a multimode laser and you can't improve beam quality with a lens.

Your pen size green laser isn't pulsed. And how do you straighten a pulse? Grab it by the two ends and pull?

Define "double up".
